How Much Do Agricultural Policies Restrict Trade? Comparing Trade Restrictiveness Indexes

Recently the Bank has provided new indicators for monitoring the extent to which agricultural policies restrict international trade in farm goods. They come from two studies with differing methodologies and data sources, and each provides less-than-perfect estimates. This note shows how and explains why the two indexes differ for some countries.agriculture, trade, farm goods, policies, trade restrictiveness, tariffs, imports, exports, quotas, World Bank

New Indicators of How Much Agricultural Policies Restrict Global Trade

Despite recent reforms, world agricultural markets remain highly distorted by government policies. Traditional indicators of agricultural and food price distortions such as producer and consumer support estimates (PSEs and CSEs) can be poor guides to the policiesÂ’ trade effects. Two recent studies provide much better indicators of trade- (and welfare-)reducing effects of farm price and trade policies, but they provide somewhat differing numbers. This paper explains why those estimates differ and how they might be improved for use in on-going annual monitoring of the trade restrictiveness of agricultural policies in both high-incmoe and developing countries.Agricultural policies, trade restrictiveness indexes, food price distortions

Changing Ccontributions of Different Agricultural Policy Instruments to Global Reductions in Trade and Welfare

Trade negotiators and policy advisors are keen to know the relative contribution of different farm policy instruments to international trade and economic welfare. Nominal rates of assistance or producer support estimates are incomplete indicators, especially when (especially in developing countries) some commodities are taxed and others are subsidized in which case positive contributions can offset negative contributions. This paper develops and estimates a new set of more-satisfactory indicators to examine the relative contribution of different farm policy instruments to reductions in agricultural trade and welfare, drawing on recent literature on trade restrictiveness indexes and a recently compiled database on distortions to agricultural prices for 75 developing and high-income countries over the period 1960 to 2004. Results confirm earlier findings that border taxes are the dominant instrument affecting global trade and welfare, but they also suggest declines in export taxes contributed nearly as much as cuts in import protection to global welfare gains from agricultural policy reforms since the 1980s.Distorted incentives, agricultural price and trade policies, trade restrictiveness index

Agricultural distortions in Sub-Saharan Africa : trade and welfare indicators, 1961 to 2004

For decades, agricultural price and trade policies in Sub-Saharan Africa have hampered farmers’ contributions to economic growth and poverty reduction. Although there has been much policy reform over the past two decades, the injections of agricultural development funding, together with ongoing regional and global trade negotiations, have brought distortionary policies under the spotlight once again. A key question asked of those policies is: How much are they still reducing national economic welfare and trade? Economy-wide models are able to address that question, but they are not available for many poor countries. Even where they are, typically they apply to just one particular previous year and so are unable to provide trends in effects over time. This paper provides a partial-equilibrium alternative to economy-wide modeling, by drawing on a modification of so-called trade restrictiveness indexes to provide theoretically precise indicators of the trade and welfare effects of agricultural policy distortions to producer and consumer prices over the past half-century. The authors generate time series of country level indexes, as well as Africa-wide aggregates. They also provide annual commodity market indexes for the region, and a sense of the relative importance of the key policy instruments used.Economic Theory&Research,Markets and Market Access,Emerging Markets,Trade Policy,Free Trade

Global Distortions to Agricultural Markets: New Indicators of Trade and Welfare Impacts, 1955 to 2007

Despite recent reforms, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions can be poor guides to the policies? economic effects. Recent theoretical literature provides indicators of trade and welfare-reducing effects of price and trade policies which this paper builds on to develop more-satisfactory indexes. The authors exploit a new Agricultural Distortion database to generate estimates of them for developing and high-income countries over the past half century. These better approximations of the trade and welfare effects of sector policies are generated without a formal model of global markets or even price elasticity estimates.Distorted incentives, agricultural and trade policies, trade restrictiveness index
